1. Chemical Name:** Disodium Phosphate
2. Molecular Formula:** Na2HPO4, Na2HPO4·2H2O, Na2HPO4·12H2O
3. Molecular Weight:** - Anhydrous: 141.99 - Dihydrate: 177.96 - Dodecahydrate: 358.14
4. CAS: - Anhydrous: 7558-79-4 - Dihydrate: 10028-24-7 - Dodecahydrate: 10039-32-4
5. Character:** - This compound appears as a white or colorless rhombic crystalline or prismatic crystal. Remarkably, it dissolves easily in water, yet remains insoluble in ethanol. Its relative density is 1.52, and it boasts a melting point of 34.6ºC. Upon heating to 180ºC, it transforms to anhydrous by losing crystal water.
6. Usage: - In the food industry, it serves as a vital agent in baking to prevent oxidation stains and acts as an emulsifier in dairy products to prevent egg white solidification. Additionally, it is used as an emulsifier and chelating agent in solid drinks, enhancing texture and stability.
7. Packing: - The product is securely packed with a polyethylene bag as the inner layer, further protected by a compound plastic woven bag on the
8.Storage and Transport: - Recommended to be stored in a dry, ventilated warehouse, this product should be kept away from heat and moisture during transportation. Handle with care to avoid any damage, and importantly, it must be stored separately from any poisonous substances to maintain safety and integrity.
